Any seasoned or professional loaders care to share the best way to load these bullets so they feed reliably in an HK USP or ParaOrdnance. My bullets are micing at 1.225 because I was steered here by a "gunsmith" but this formula didn't work. I would get 40% failure to chamber after 100-125 rds through a clean gun. I would have to pull back the slide slightly and release to get the round to slide forward. I use Win. 231, beginning load, on a Dillon 550. I can't tell if it is the powder that fouls the chamber and does this or if the bullets are too short. Any ideas from anyone??? Thanks in advance...
